2016-07-26Input: synaptics-rmi4 - do not check for NULL when calling of_node_put()Markus Elfring1-4/+1
The of_node_put() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

2016-07-26Input: cros_ec_keyb - cleanup use of devDouglas Anderson1-10/+9
In cros_ec_keyb we stored "dev" in "struct cros_ec_keyb", but this was the EC's dev pointer and not the keyboard's. Let's clean this up to make it the keyboard's dev pointer. This could be useful in future patches but also has the nice effect of changing a few printouts to include the name of the keyboard device instead of the EC device, so we will see: [ 1.224648] cros-ec-keyb ff110000.spi:ec@0:keyboard-controller: valid_keys[00] = 0x14 instead of: [ 1.224505] cros-ec-spi spi0.0: valid_keys[00] = 0x14 Signed-off-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Brian Norris <briannorris@chromium.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2016-07-14Input: synaptics-rmi4 - use of_get_child_by_name() to fix refcountAndrew Duggan1-2/+2
Calling of_find_node_by_name() assumes that the caller has incremented the refcount of the of_node being passed in. Currently, the caller is not incrementing the refcount of the of_node which results in the node being prematurely freed when of_find_node_by_name() calls of_node_put() on it.

2016-06-23Input: vmmouse - remove port reservationSinclair Yeh1-20/+2
The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource. This causes the port to be reserved by the APCI module as the system comes up, making it unavailable to be reserved again by other drivers, thus preserving this VMWare port for special use in a VMWare guest. This port is designed to be shared among multiple VMWare services, such as the VMMOUSE. Because of this, VMMOUSE should not try to reserve this port on its own. The VMWare non-EFI BIOS does not do this to preserve compatibility with existing/legacy VMs. It is known that there is small chance a VM may be configured such that these ports get reserved by other non-VMWare devices, and if this ever happens, the result is undefined.

2016-06-23Input: xpad - fix oops when attaching an unknown Xbox One gamepadCameron Gutman1-10/+13
Xbox One controllers have multiple interfaces which all have the same class, subclass, and protocol. One of the these interfaces has only a single endpoint. When Xpad attempts to bind to this interface, it causes an oops when trying initialize the output URB by trying to access the second endpoint's descriptor. This situation was avoided for known Xbox One devices by checking the XTYPE constant associated with the VID and PID tuple. However, this breaks when new or previously unknown Xbox One controllers are attached to the system. This change addresses the problem by deriving the XTYPE for Xbox One controllers based on the interface protocol before checking the interface number.

2016-05-27Input: xpad - prevent spurious input from wired Xbox 360 controllersCameron Gutman1-0/+4
After initially connecting a wired Xbox 360 controller or sending it a command to change LEDs, a status/response packet is interpreted as controller input. This causes the state of buttons represented in byte 2 of the controller data packet to be incorrect until the next valid input packet. Wireless Xbox 360 controllers are not affected. Writing a new value to the LED device while holding the Start button and running jstest is sufficient to reproduce this bug. An event will come through with the Start button released. Xboxdrv also won't attempt to read controller input from a packet where byte 0 is non-zero. It also checks that byte 1 is 0x14, but that value differs between wired and wireless controllers and this code is shared by both. I think just checking byte 0 is enough to eliminate unwanted packets. The following are some examples of 3-byte status packets I saw: 01 03 02 02 03 00 03 03 03 08 03 00 Signed-off-by: Cameron Gutman <aicommander@gmail.com> Signed-off-by: Pavel Rojtberg <rojtberg@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
